ascii lists ASCII idiomatic names and octal/decimal code-point forms. It provides easy conversion between various byte representations and the American Standard Code for Information Interchange (ASCII) character table. It knows about a wide variety of hex, binary, octal, Teletype mnemonic, ISO/ECMA code point, slang names, XML entity names, and other representations. Given any one on the command line, it will try to display all others. Called with no arguments, it displays a small, handy ASCII chart.

ckmame is a program to check ROM sets for MAME, the Multiple Arcade Machine Emulator. It tells you which ROM files are missing or have an incorrect checksum, and can delete unknown and unused files from the ROM sets, and rename or move ROM files.

Galaxis is a curses-based clone of Christian Franz's game Galaxis for the Macintosh. It is a logic puzzle--you must drop probes in space to locate four lifeboats from a distressed interstellar liner. Can you locate them all before you run out of probes and they run out of oxygen?

doclifter helps with lifting documents with nroff markup to XML-DocBook. Lifting documents from presentation level to semantic level is hard, and a really good job requires human polishing. This tool aims to do everything that can be mechanized, and to preserve any troff-level information that might have structural implications in XML comments. TBL tables are translated into DocBook table markup, PIC into SVG, and EQN into MathML (relying on pic2svg and GNU eqn for the last two).

This program is a calculator for card-draw
probabilities. Specifically, it computes
non-replacement draw probabilities using the
hypergeometric function. It can also be used to
compute binomial coefficients and the gamma function.

greed is a strategy game. When you move in a direction, you erase N grid squares in that direction, N being the first number in that direction and your score for the move. You cannot move onto a space you have already eaten, and the game ends when you cannot move.
